' Applicationfiled October 15, 1912. Serial No. 725,860.

To all whom it may concern:

Be it known that I, HERMAN A. WEBER, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Spark-Arresters and Smoke-Treatin Devices, of whichthe following is a spec' cation.

My invention relates to a combined spark arrester and smoke treating devicefor use in connection with-steam engines. V

One object of my invention is to provide a device wherein llve sparks are prevented from escaping to the atmosphere, the temperature of the products of combustion be ing materially reduced previous to its escape to the atmosphere.

Another object of my invention is to provide means in a smoke chamber to drive the smoke and cinders inwardlyso that they will be treated and discharged adjacent the lower part of the chamber. I

Other objects will hereinafter appear as the preferred embodiment of the invention is described in connection with the accompanying drawings, wherein- Figure 1 is an end view ofthe boiler of a steam engine showing the invention in connection therewith, and, Fig. 2 is a vertical sectional view through the same parts.

Referring to the drawin s, 1 designates that portion of the boiler o a steam engine into which the smoke passes for escape through a usual Smokestack. In place of the usual smoke stack I have rovided a stack or upper chamber 2 which is closed at its top and secured to the boiler portion 1 by bolts or rivets 3 or in any other suitable manner. Across the stack 2 extends a partition designated 4 which provides a pas?" sa eway 5 for the escapingsmoke and anot er passageway in which is secured a hopper or receptacle 6 provided with outlet openings at opposite ends. The numeral 7 designates a cinder discharge chute which is provided with inlet openings on opposite sides thereof. The discharge chute 7 opens' into the boiler part 1 and is secured thereto in any suitable manner. Arcuate channel members 8 are secured exterior of the boiler part 1 as by meansof bolts 9, which members 8 have their hollow portions at one end register with the openings of the chute 7, and which hollow members at their opposite ends enter the stack 2 and have their openings register with the openings of the receptacle 6. In the discharge chute 7 is re-.

movably mounted a valve or slide designated 1O which-has a projection -extending through the .wall of said chute, which is provided with a flange 12 to which is secured an operating handle 13. A revoluble fan member 14 is mounted on a frame 15 located in a side opening 16 of the stack 2 A smoke flue or duct conslsting of a connection of pipes 17 leads from the stack 2 and is connected to a smoke treating Chamber 18 in any suitable manner, wh ch chamber is, supported in any suitable manner preferably exterior of the holler portion as upon the running-board of the engine which is designated 17. In said chamber are provided a number of staggered baffle plates 19 to provide a tortuous passage for the escaping smoke. An outlet mm 20 is connected to the smoke treating chamber, thereby providing for the ultimate escape of the products of combustion,

preferably at a 'pointbelow and at one'side i of the boiler 1. I

Above the receptacle 6 and adjacent the outlet openingifor the pipe connection 17 will strike against the plate 21 and be deflected or fall into the receptacle '6, from whence 151. .Will pass th'roughthe passages of thej channelmemb'ers 8 and into the dis charge chute 7,'resting upon the slide '10.

When a quantity of cinders have collected in the discharge'chute and passages of the channel members, said slide may be withdrawn in order to discharge said cinders. The smaller cinders, live sparks, and smoke passing through the duct will be discharged into the smoke treating chamber 18 and will follow a tortuous or broken passage between the ba'flle plates thereof, being finally discharged to the atmosphere through the discharge pipe 20, the live sparks having by this time been subdued. I

It is to be'understood that I have described and illustrated herein the preferred embodiment of my invention only, and that chute, means for directing the cinders into.

the hopper, of an air driven fan arranged adjacent an opening formed within the said chamber, the said opening being arranged to receive a direct current of air during the forward travel of the locomotive, a chamber outlet pipe, a smoke treating chamber into Which the said pipe discharges, a plurality of battle plates arranged within the said chamber, and an outlet pipe connected to the said chamber adapted to discharge the treated smoke to the atmosphere at a point adj acent the ground, as and for the purpose. set forth. I

2. In a spark arrester and smoke treating device for locomotives, the combination of a discharge chamber for the products of combustion, a hopper disposed Within said chamber, a cinder discharge chute, arcuate channels communicating the said hopper with the said chute, an arcuate baflie plate disposed to direct the cinders into the hopperyand means carried by said chute for controlling the outlet thereof, of an air driven fan arranged adjacent an opening formed Within the said chamber, the said opening being disposed to receive a direct current of air during the forward travel of the locomotive, a .pipe leading from the said chamber exteriorly of the locomotive and to one side thereof, the said bafile being arranged adjacent the pipe'opening, a smoke treating chamber into which the smoke is conveyed, a plurality of spaced positely extending baflle plates arranged v ithin the said chamber, and an outlet pipe connected to the opposite end of thezsaid chamber from that of the said first mentioned pipe, the said outlet adapted'to discharge the treated smoke to the atmosphere at a point adjacent the ground and at one side of the comotive.

3. In a spark arrester and smoke treating device for locomotives, the combination of smoke stack having a discharge chamber formed therein adapted to receive the products of combustiom'a partition arranged withlnthe said smoke stack, a hopper disposed within the said chamber, a cinder dis charge chute, arcuate channels communicating the said hopper with the said chute, an-

arcuate bafiie plate depending from the top of the said stack, the said platebeing disposed to direct the-cinders" into the said hopper,- and Valve means carried by the said chute for controlling the outlet thereof, of an air driven fan arranged Within an opening formed Within the said stack anddisposed to receive a direct current of air during the forward travel of the locomotive,

the said air current adapted to direct the product of combustion agalnst the said are- :uate baffle plate, a pipe leading from the said chamber at a point adjacent the said bafile, a smoke treating chamber arranged exteriorly of the locomotive into which the said pipe extends, a plurality of uniformly and at one side of the locomotive, as and for the purpose set forth.
